To all whom it mag/concern:

Be it knownthatI, SOLOMON O. CHASE, a" citizen of the United States, residing at North Baltimore, in the county of Woodand State of Ohio, have invented a new and useful Vapor-Burner, of which thejfollowingis a specifieation.

My invention relates to vapor or fluid fuel burners,the objectpin view being to provide a simple, inexpensive, and efficient device forburning petroleum and other crudeoils,` whereby the pressure of the` fuel atthe burner or point of ignition is equalized,irrespective of the pressure at the point of supply, to prevent flooding the burner and insure a steady and perfect combustion, and at the Sametime to provide a device capable of use with safety by those inexperienced in the manipulation of burners of this class.

Further objects and advantages of the invention will appear in the `following description, and theV novel features thereof will be particularly pointed out in the appended claims.

In thedrawingsz-Figure 1 is a plan view of a burner constructed in accordance with my invention. Fig. Zis a vertical section of the same on the'linc 2-f.. of Fig. 1, the apparatus being shown in the lire-box of a stove. Fig. 3 is a detail section through the perforated portion ofthe burner-tube to show the drip perforation and subjacent initial ignition pan. Fig. 4 is a detail ,enlarged section of the safety valve. Fig. 5 is a similar view of the straining device.

Similar numerals of reference indicate corresponding parts in all the' figures of the drawings.

1 designates a supply-pipe Vextending from a suitable reservoir, `not shown; 2, a superheating pipe, and 3 theburner-tube, which is located below and in close proximity to the superheating pipe, and is .U -shaped in Vconstruction. The supply-pipe is provided at a suitable point outside of the casing of the stove, which is represented at ein Fig. v2, with a main valve 5, preferably of the construction known as needle-valve, and'introduced between adjacent portions of the supply-pipe at apoint between this main valve and the 5o reservoir, not shown, is a straining device 6, constructed of acylindrical casing 7 provided at one side with a removable plug 8 and at itsends with removable caps 9, said plug S beingprovided for the purpose of facilitating the insertion and removal of absorbent packing 10 of sponge, cotton, or similar material. This straining device retains scales and other hard substances which may be introduced into the-pipes by the fuel, and prevents the 6o same from reaching the main valve.

11 and 12 represent axially aligned cylinders arranged adjacent to the burner-tube, and communicating with thelow temperature cylinder 11 is the adjacent portion of the sup- 65 ply-pipe, the latter being provided at its upper side within the cylinder with an outlet perforation 13. The low temperature cylinder 11 is connected with the high temperature cylinder 12 by means of an interposed 7c pipe 14, having a vertical central portion 14:,

a lower horizontal portion 14", which communicates with said low temperature cylinder, and an upper horizontal portion 14, which communicates with the high temperature cyl- 7 5 inder, and is provided with an outlet perforation 15 within said high temperature cylinder. The connection between the upper end of the vertical portion 11i and the adjacent extremity of the horizontal portion la is ac- 8o complished by means of a T-coupling 14d, in the upper arm of which is arranged a removable plug la. In the vertical portion 14a is arranged the stem of a restraining valve 16, which is adapted to be received by the adja- 8 5 cent seat 16, the pressure of the fluid in the l pipes against said valve normally holding the latter out of Contact with its seat, or unseated as shown in Fig. 2. Carried by the valve is an upwardly extending stud 16C, which is 9o adapted to engage with the lower end of the plug 14:e to limit the upward movement of the valve. The super-heating pipe is connected with the high temperature cylinder adjacent to the plane of the lowerV side of the latter, and after extending horizontally to the outer or remote end of the burner-tube is bent upon itself and extends the entire length of the "fr burner tube to the inlet end of the same, where it is provided with a needle regulating valve 17 communicating with a mixer 18 ar ranged upon the end of the burner-tube and open at its larger end 19 for the admission of air. As the fuel is projected into the inlet end of the burner-tube it produces a partial vacuum which has the effect of inducting a certain amount of atmospheric air, which becoming mixed with the fuel assistsin the complete combustion thereof.

The burner-tube, as above mentioned, is U- shaped with the enlarged or bell-shaped portion 19 thereof formed on the extremity of an imperforate arm 3, while the other parallelW arm 3b is provided with a series of burner perforations 2l for the escape of the gaseous fuel. Thus the fuel must pass through the entire length of the arm 3 before reaching the perforated portion of the tube, thus providing for an effective intermixture of the gas and air before the point of ignition is reached. This arm 3b of the burner-tube is provided in its lower side and at its center with a single drip-perforation 22 arranged over a drip-pan 23.

Inserted in the supply-pipe between the main valve and low temperature cylinder is a safety or check-valve 24, comprising a stem 25, which carries a single valve-head or disk 26, a valve-seat 28 formed in the casing containing said Valve or disk, and a spring 29 coiled upon the stem of the valve or disk to normally hold the valve-head or disk out of contact with its seat. Said head or disk is provided with a stud 27 to engage the lower end of a removable plug 27a arranged in the upper end of the valve-casing to limit its up! Ward movement, as above described in connection with the valve which is interposed between the low and high pressure cylinders. The function of the spring which is used in connection with the valve 24 is to support the weight of the stem and the valve-head or disk and prevent the sticking of said head or disk and the clogging of the openin g by small particles or impurities which may pass the straining device.

In operation the main valve is open to admit oil, which iows through the supply-pipe and straining device into the low temperature cylinder, thence through the interposed valved connecting-pipe into the high temperature cylinder, from the latter into the superheating pipe, and inallyinto the burner-tube. From the burner-tube the oil flows through the perforation 22 into the subjacent pan 23, where itis ignited,and when the burner-tube and adjacent parts have become sufficiently heated to vaporize the oil contained therein the needle-valve 17 is adjusted to allow the desired pressure and the main valve is turned to admit the full pressure of the supplyfrom the reservoir. It will be seen that this needle or regulating valve has full control of the apparatus whether a small or large combustion is allowed 'at the point of ignition. In other words, said needle valve acts independently of the main valve after the burner has been started, and by closing said valve, the gas Within the apparatus is con ned, thus causing the pressure to close the safety-valves 16 and 27. In the same way an excessive pressure in the burner-tube will cause the closing of said check-valves and will maintain the same in their closed positions until the pressure is relieved sufficiently to allow the actuating springs connected with said valves to reopen them to permit further flow of fuel. It is obvious that the tension of these actuating springs is assisted by the pressure of the fuel in the supply-pipe. y y

Any solid 'particles contained in the oil which may pass the straining device and the main valve are deposited in the cylinders and are there subjected to a degree of heat to cause disintegrating without resulting in the choking or clogging of any of the pas-l sages of the apparatus.

The check-valve 16 which is interposed between the cylinders is preferably arranged in a vertical position, as above described, to permit of the passage of carbon and other solid particles in the fuel without obstructing the passage, and also to allow said cylinders to be arranged in close proximity to each other. I

It will be obvious that various changes in the form, proportion, and the minor details of construction may be resorted to withoutdeparting from the spirit of the invention or sacrificing any of the advantages thereof.

Having described my invention, what I claim is- 1. In a fluid fuel burner, the combination with a supply-pipe, of a U-shaped burnertube having parallel arms arranged in a common horizontal plane, one of said arms being closed at its extremity and provided with burner openings, and the other of said arms being open at its extremity and imperforate throughout, axially aligned cylindrical retorts arranged above the imperforate arm of the burner-tube with their axles parallel therewith, a connecting-tube between said retorts, the intermediate portion of said tube being vertical, a check-valve arranged in the vertical portion of the connecting-tube, a super-heating pipe communicating with one of the retorts, extending horizontally and longitudinally over the burner-tube and having a valved terminal inserted in the open end of the imperforate arm, substantially as specified.

2. The combination with a burnertube, of co-axial retorts arranged above the burnertube and communicating with each other by a connecting-tube having a check-valve, a super-heating pipe arranged vertically over the burner-tube and provided with a valved IOC outlet communicating with the inlet end of the burner-tube, anda cheek-valve arranged in the supply-pipe in operative relation with a seat, said valve being provided with a spring which normally holds it ont of Contact with its seat but which is adapted to yield to allow the seating of said valve when back pressure is produced in the supply-pipe, substantially as specified.

In testimony that I claim the foregoing as 1o my own I have hereto affixed my signature in the presence of two witnesses.
